So I'm putting in the rebuilt 289 in my 66 tomorrow and I know the procedure for how to break in the cam but I've got a question. Not only is the engine rebuilt, but the pumpkin in the rear is new also and that has its own break in procedure.

I started my mustang for the first time today since I put a new motor.
Its a 5.0 roller motor and its either brand new or factory refurbished I think.
GT40 or GT40p heads (I think, could be E40 or something weird)
Full exhaust, no cats, no EGR no smog pump, no A/C.
